Industrial Touch Screen Frequently Asked Questions

Compatibility / Installation

How can I get the drivers I need?

You can download all our drivers from our driver download page. [collapse]

What operating systems do you have drivers for?

We currently have drivers for all current and past versions of Microsoft Windows (including CE and Embedded versions), Apple Mac OS, and Linux. Legacy drivers are also available for Microsoft DOS and IBM OS/2.

You can download all our drivers from our driver download page.

We can also provide machine-independent sample source code in C for writing your own low-level interface. [collapse]

How far away can the touch screen be from the computer?

When using our Industrial KVM extenders, a touch screen or monitor can be placed up to 300 m (1000') from the display with both touch (USB) and video (VGA) signals passing over a single CATx cable. For shorter range extension a 60 m (198') extender is also available.

If a serial port is available on the PC, distances of up to 15 m (50') can be achieved using simple serial cable (touch) and VGA cable (video).

For workstations only requiring video (no touch screen), long VGA cables of up to 15 m (50') can be used, or a VGA extender can be used up to distances of 150 m (500').

Please see our KVM Extender and Cabling Options pages for full details. [collapse]

My environment contains -------- chemical. Will this harm my touch screen?

Please see our Chemical Resistance page for full details. [collapse]


Will my touch screen work while wearing gloves?

Yes. All of our touch screens use resistive touch technology, which is pressure sensitive and will work with a finger, thick gloves, or even a stylus of any material. [collapse]

Can I use both my touch screen and mouse at the same time?

Yes. Our drivers work with your existing mouse. Each pointing device will move the cursor. [collapse]

Can I use touch screens on multiple monitors on the same computer?

Yes. Our touch screen drivers allow multiple monitors connected to a single PC whether in mirroring mode (multiple screens showing the same desktop) or extended desktop (a single desktop stretched across multiple displays).

Our Windows drivers allow each touch screen to be calibrated independently whether you are using USB or Serial for connection to the PC. Please contact our support department for information on how to set this up. [collapse]

What is the response time for the touch screen?

Resistive touch controllers sense the quickest possible tap (contacts of only 30ms). Response time is perceived as immediate unless the application does not give proper feedback. [collapse]

Cleaning / Maintenance

How often is it necessary to recalibrate?

After initial setup, the touch screen should not need recalibration.  Installing new drivers could erase a previous calibration.  Also, some users prefer a different calibration style (e.g.: pointer centered on the finger-tip vs. centered on the finger). [collapse]

How reliable is a touch screen?

There is no standard way of measuring MTBF (Mean Time Between Failure) for a touch screen, but our resistive touch screens have been tested to more than 35 million touches in one spot with a stylus similar to a finger. The touch screen controller MTBFs are typically 2-4 times longer than that of the display. [collapse]

Are fingerprints and dirt a problem on touch screens?

Dirt, fingerprints, and liquid do not affect the operation of a properly sealed resistive touch display. Use bright, patterned background colors to minimize the visual effects of dirt and fingerprints. [collapse]

What can I use to clean the touch screen?

Any standard glass cleaner can be used to clean the touch screen. For non-sealed units, always spray the glass cleaner on the cloth or towel and then clean the touch screen. [collapse]

Will vinegar or ammonia hurt the touch screen?

No, but be careful that liquids do not leak inside non-sealed units. Spray the cloth and then clean the touch screen. [collapse]
